COMPOSITION OF MATTER FOR BLEACHING- AND CLEANING.

No Drawing.

To all whom it may concern Be it known that I, WILLIAM B. FINK, acitizen of the United States, and a resident of New York, county andState of New York, have invented a certain new and useful Improvement inCompositions of Matter for Bleaching and Cleaning, of which thefollowing is a full, clear, and exact specification. Y

My composition has for its object to provide a bleecher and cleanserdesigned to be employed in laundries, woolen mills, silk mills, andother similar places, for cleaning wearing apparel and other articleswhich are made of linen, cotton goods, or other Washable fabrics, andwhich serves to effectually bleach and cleanse the articles Withoutdamaging the goods, oriadingjghe most delicate colorings thereof as wellas saving the consumption of thirty to fifty per cent. of the soapordinarily used, and also permitting the employment of injuriouschlorids and acid bleaches to be dispensed with.

.My composition of matter consists of the following ingredients,combined in the proportions stated, viz :calcium oxid '(unslaked lime) 7pounds, potassium carbonate 25 pounds, potassiumopermanganate -l pound,ammoniumichlorid (sal-ammoniac) 2 pounds, sodium biborate (borax) 12pounds, water, sufficient quantity to make 48 gallons.

The ingredients are placed in a barrel, or

other suitable receptacle. and then dissolved in four gallons of boilingwater by agitation in any preferred manner. The remainder 'of the wateris then added to the mixture which is allowed to stand until all solid'surplus substances have been deposited upon the bottom of thereceptacle. In prac- Specification of Letters Patent.

tice only the clear liquid is used. For washing laundry a proportion ofone-third of the liquid and two-thirds of neutral soap are boiledtogether and this mixture is used 4::

in the manner incident to the methods ordinarily employed in laundries.

While in the foregoing I have embodied thepreferred formula of mycomposition of matter, I do not wish to be understood as 5i? limitingmyself to the exact proportion of the ingredients as mentioned, as I amaware that changes may be made therein, therefore I reserve to myselfthe right to vary the proportions of the ingredients as well aseliminate one or more of said ingredients, in

order to meet the requirements for the use of the composition asoccasion demands.

Having thus described my invention, I

claim as new and desire to secure by Let- (it ters Patent: 1

1. The herein described composition of matter formed by mixing calciumoxid, potassium carbonate, potassium permanganate,

sodium biborate, ammonium chlorid, and

water, substantially as described and for the purpose specified.

2. The herein described composition of matter formed by mixing calciumoxid seven pounds, potassium carbonate, twenty-five
